What is thermonuclear fusion? - Socratic
Thermonuclear fusion is a way of achieving nuclear fusion using extremely high temperatures. There are two types of thermonuclear fusion; controlled and uncontrolled. Controlled thermonuclear fusion occurs in an environment where the energy produced can be harnessed for constructive purposes, while uncontrolled thermonuclear fusion occurs in thermonuclear …
What is hydrogen shell fusion? - Socratic
2016年6月7日 · Hydrogen shell fusion is hydrogen fusion reactions taking place in a shell around a helium fusing core. When a star has depleted its supply of hydrogen in its core, the core is mainly helium. At this stage the core contacts and the temperature rises. The star enters the red giant stage. Around the helium core there is a shell of hydrogen. Fusion reactions continue in …
In the life cycle of a star, how does a red giant become a planetary ...
2015年11月17日 · After burning up it's fuel. Basically a Red Giant is formed when a Star like our Sun burns all of it's hydrogen to helium and then rearranges itself. This process takes about 10 Billion years. After becoming a Red Giant the Sun will become bigger and more denser than it is today. At this time it will start burning Helium to Carbon for a few hundred million years until it …
Is the source of the sun's energy nuclear fusion or nuclear
2014年5月29日 · The source of the sun's energy is Nuclear Fusion :) Basically, the heat generated within the sun causes the nuclei which would normally repel one another (because they both have a positive charge) to bang into one another and fuse. As a result of the fusion, a new atom is created. Example: H + H --> He If you add the atomic numbers of the reactant atoms …
The granular appearance of the surface of the Sun is evidence of …
2016年4月14日 · Convection currents occurring be,low. Hot gases goes up due to connection currents.
How is nuclear fusion in a main-sequence star different from
2018年3月17日 · When a smaller star runs out of Hydrogen in its core, fusion stops and the core collapses. It heats up until Hydrogen fusion can take place in the Hydrogen shell around the Helium core. This causes the outer layer of the star to expand into a red giant. So, a main sequence star is fusing Hydrogen into Helium in its core.
How is the sun an example of nuclear energy? - Socratic
2017年10月15日 · Nuclear energy is what powers the sun. The material of the sun (primarily hydrogen) contracted into into itself by gravitation to form the body. The extreme pressure forced the hydrogen atoms to fuse (fusion) into helium, releasing huge mounts of energy. As stars age this process not only continues, but advances to the formation of heavier elements as well. …
In what part of the sun's interior do nuclear reactions occur?
2018年4月20日 · The "Core". The power generator in the Sun is in its center, buried deeply within it. It is called "the core", with a radius close to one fourth of that of the star. In the core, pressures and temperatures are high enough to force fusion, that is, nuclear reactions whereby some nuclei merge to make others. It is the type of reaction that powers a hydrogen bomb. The most …
Nuclear reactions in the sun’s interior convert what ... - Socratic
2016年4月19日 · In the core of Sun hydrogen atoms are fused into helium atoms. 4 hydrogen atoms fuse into 1 Helium atom and remaining 0.7% of mass is converted into energy as per E= MC^ 2. This reaction is known a s proton proton chain. Picture credit quora.com.
How much of the total energy that leaves the sun makes it to
2016年8月19日 · We intercept (pi*d^2)/4 = "113,097,335 km"^2 We're "150,000,000 km" apart on average. Earth is only "12,000 km" in diameter. The sun emits in all directions. We subtend a tiny surface when viewed from the sun, with a small fraction in the line of its energy. At "150,000,000 km", the surface is the area of that sphere, which is equal to "area" = 4 * pi * "150,000,000 …
